Juan was kind enough to linger on site, and work on a production machine, to try the parameter to make the system stable. He discovered that reducing the maximum transfer size issued to the adapter to 128KB stabilized his system. This is related to an earlier change for the 2.6.13 tree resulting from Martin Drab's testing where the transfer size was reduced from 4G to 256KB; we needed to go still further in scaling back the request size. Here is the patch that tames this regression. Signed-off-by: Mark Salyzyn <aacraid@adaptec.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com> |

AACRAID Driver for Linux (take two) Introduction ------------------------- The aacraid driver adds support for Adaptec (http://www.adaptec.com) RAID controllers. This is a major rewrite from the original Adaptec supplied driver. It has signficantly cleaned up both the code and the running binary size (the module is less than half the size of the original). Supported Cards/Chipsets ------------------------- Adaptec 2020S Adaptec 2025S Adaptec 2120S Adaptec 2130S Adaptec 2200S Adaptec 2230S Adaptec 2240S Adaptec 2410SA Adaptec 2610SA Adaptec 2810SA Adaptec 21610SA Adaptec 3230S Adaptec 3240S Adaptec 4000SAS Adaptec 4005SAS Adaptec 4800SAS Adaptec 4805SAS Adaptec 5400S Dell PERC 2 Quad Channel Dell PERC 2/Si Dell PERC 3/Si Dell PERC 3/Di Dell CERC 2 HP NetRAID-4M Legend S220 Legend S230 IBM ServeRAID 8i ICP 9014R0 ICP 9024R0 ICP 9047MA ICP 9087MA ICP 9085LI ICP 5085AU People ------------------------- Alan Cox <alan@redhat.com> Christoph Hellwig <hch@infradead.org> (updates for new-style PCI probing and SCSI host registration, small cleanups/fixes) Matt Domsch <matt_domsch@dell.com> (revision ioctl, adapter messages) Deanna Bonds (non-DASD support, PAE fibs and 64 bit, added new adaptec controllers added new ioctls, changed scsi interface to use new error handler, increased the number of fibs and outstanding commands to a container) (fixed 64bit and 64G memory model, changed confusing naming convention where fibs that go to the hardware are consistently called hw_fibs and not just fibs like the name of the driver tracking structure) Mark Salyzyn <Mark_Salyzyn@adaptec.com> Fixed panic issues and added some new product ids for upcoming hbas. Original Driver ------------------------- Adaptec Unix OEM Product Group Mailing List ------------------------- linux-scsi@vger.kernel.org (Interested parties troll here) Also note this is very different to Brian's original driver so don't expect him to support it. Adaptec does support this driver. Contact either tech support or Mark Salyzyn. Original by Brian Boerner February 2001 Rewritten by Alan Cox, November 2001
